New Phytologist, Volume 243, Issue 5, Page 1840-1854, September 2024.Summary The B chromosomes exhibit diverse behaviour compared with conventional genetic models. The capacity of the B chromosome either to accumulate or to be eliminated in a tissue‐specific manner is dependent on biological processes related to aberrant cell division(s), but here yet remains compatible with normal development.

OsALKBH9‐mediated m6A demethylation regulates tapetal PCD and pollen exine accumulation in rice
Plant Biotechnology Journal, Volume 22, Issue 9, Page 2410-2423, September 2024.Summary The N6‐methyladenosine (m6A) mRNA modification is crucial for plant development and stress responses. In rice, the male sterility resulting from the deficiency of OsFIP37, a core component of m6A methyltransferase complex, emphasizes the significant role of m6A in male fertility. m6A is reversible and can be removed by m6A demethylases. However,

Aggregations of organelles in meiotic cells of higher plants
Acta Societatis Botanicorum Poloniae, 2014 During early prophase I in microsporocytes and sporocytes of various plants all mitochondria and plastids aggregate in a group, where some plastids seem to undergo division. This group desintegrates by middle prophase I.

International Biological Flora: Ceratonia siliqua
Journal of Ecology, Volume 112, Issue 8, Page 1885-1922, August 2024.The carob tree (Ceratonia siliqua) has a long traditional history in Mediterranean cultures providing food for humans and domestic animals. Its remarkable tolerance of drought, salt and fire, with an ability to thrive in poor, dry soils, makes it ideal for a warming Mediterranean climate.

Why are the inner and outer sides of many flower petals differently coloured?
Plant Biology, Volume 26, Issue 5, Page 665-674, August 2024.Evolutionary hypotheses aimed at explaining why inner and outer sides of petals are often differently coloured. Abstract The flower perianth has various, non‐mutually exclusive functions, such as visual signalling to pollinators and protecting the reproductive organs from the elements and from florivores, but how different perianth structures and their

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana
Plant Direct, Volume 8, Issue 7, July 2024.Abstract Cytoplasmic projections (CPs) formed by the generative and sperm cells link the male gametes with the vegetative cell (VC) nucleus, which are required to build the male germ unit (MGU) assemblage in the angiosperm pollen grain. As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized
